batteries become weak.
Use and care for laser level
To use the laser level properly and keep your work
accurate:
The laser level must be set where it is not exposed to
rain.
Replace all the batteries (2 pieces) at one time with new
alkaline ones.
Do not expose the laser level to extreme temperatures
and temperature variations.
The laser level is a very precise measuring instrument.
Handle the laser level very carefully not to drop it or give
strong impacts to the outside of the tool-body.
Always check the accuracy of laser before use.
When you finish your work, always be sure that the laser
level is switched off and the laser-beam lines is not
projected.
Always keep the laser level in the carrying case when it
is carried.

Inspection of the leveling accuracy of the
laser level
Check the leveling accuracy of the unit (laser level)
Direct the vertical laser line to the string of
plumb-bob. Then adjust the vertical laser line
to the lower end of the string. Make sure that
deviation from the vertical laser line to the
upper end of the string is within the leveling
accuracy specified.
periodically in the following manners:
Fig. 7
1.
Check the leveling accuracy of horizontal
laser-beam line.
1)
Place the unit on the floor of an indoor corner
at the point of 3 to 5 m from the one wall and
1 m from the another one. (See the Fig.7)
Turn the level adjusting ring (9 ) so that the
air-bubble in the round vial (4) is centered.
Turn on the power switch (12).
2)
3)
Turn the unit and mark both ends of laser line
projected on the both walls.
4)
Then turn the unit on both sides. Make sure
that half of the deviation from laser line to the
first marked point is within the leveling
accuracy specified.
2.
Check the leveling accuracy of vertical
laser-beam line.
Fig. 8
1)
Hang a plumb-bob (See the figure 8) from 3
m height of the wall (the height of ceiling is
approx. 3 m).
Place the unit on the floor at the point of 2 to
5 m away from the wall. Make sure that the
air-bubble is centered in the round vial (4).
